I noticed that it is not easy to grant (Add-MailboxFolderPermission) mailbox folder permission for a resource mailbox (e.g. room, shared, equipment).

Note: The Identity parameter specifies the recipient and folder that you want to change the permissions for. This parameter takes the following format: <SMTP Address or Alias of Recipient>:<Folder path>. The following is an example: john@contoso.com:\Calendar. In my case it is \Kalenteri because of Finnish language. How to determine the right value for the folder path use for example Get-MailboxFolderStatistics “alias” | select Folderpath

451 4.4.0 Primary target IP address responed with:"451 5.7.3 Must issue a STARTTLS command first." Attempted failover to alternate host, but that did not succed. Either there are no alternate hosts, or delivery failed to all alternate hosts.

Well I check also related send connector and it has used RequireTLS:$true.

CheckTLS.com gave me answer: TLS is not an option on this server – TLS Adv failed

Destination’s MX servers do not support TLS (STARTTLS extension). And all messages addressed there through the send connector which required TLS (encrypted transmittion) did not pass.

What is Calendar Repair Assistant

CRA is feature of Exchange 2010 SP1+, which is not enabled by default, but should repair inconsistencies and conflicts between meeting organizer and meeting attendees within the future window (Default is 30days in advance).

CRA can log the changes so it is possible to have track back of changes

Exchange 2010 / 2013 can be designed so, that multiple mailbox tiers can be placed within one database. In this case there is not easy way how to control mailbox limits for bigger companies. I wrote the script, which can help managing limits based on single value in Custom attribute 12.
